Japanese-American life after World War II

On February 19, 1942, shortly after Japan's surprise attack on Pearl Harbor in Hawaii, President Franklin D. Roosevelt signed Executive Order 9066 authorizing the forced removal of over 110,000 Japanese Americans from the West Coast and into internment camps for the duration of the war. The personal rights, liberties, and freedoms of Japanese Americans were suspended by the United States government. In the "relocation centers", internees were housed in tar-papered army-style barracks. Some individuals who protested their treatment were sent to a special camp at Tule Lake, California.

The unanimous Supreme Court decision Ex parte Endo in December 1944 ruled that the U.S. government could not continue to detain a citizen who was "concededly loyal" to the United States. Word of the upcoming ruling led to the rescinding of the exclusion orders and allowed Japanese Americans to return to the American West Coast starting in January 1945. Many Japanese Americans suffered harsh treatment after leaving the internment camps. Examples include exclusion from being hired by jobs in the LA county, and being shut out by the produce industry, which was the lifeblood of many Japanese Americans prior to WWII.

Japanese-American Evacuation Claims Act
In 1948, President Harry S. Truman signed the Japanese-American Claims Act. This act was a way to compensate Japanese Americans for their economic losses due to their forced evacuation. Although some $38 million was paid out through provisions of the act, it would be largely ineffective even on the limited scope in which it operated.

McCarran-Walter Act
When the war ended, the American opinion of Japanese was altered. Japan was in the process of rebuilding with the help of the U.S. military. Japanese became known for their intelligence, amiable relations, and hardworking ethic. The new perspective of this country changed American minds about Japanese. In 1952, this new opinion of the Japanese resulted in first-generation Japanese Americans receiving the right to become naturalized U.S. citizens with the McCarran-Walter Act.

1965 Immigration Act
The Immigration and Nationality Act amendments of 1965 eliminated the national origins quota that was established by the United States in the Immigration Act of 1924. Emanuel Celler proposed the 1965 Act, which was strongly backed by Senator Ted Kennedy. This legislation “created the foundation of today’s immigration law.”

Congress’s investigation of WWII Japanese-American imprisonment
The Commission on Wartime Relocation and Internment of Civilians (CWRIC) was appointed by the U.S. Congress in 1980 to conduct an official governmental study into the internment of Japanese Americans during World War II. It concluded that the incarceration of Japanese Americans had not been justified by military necessity.

Civil Liberties Act
The Civil Liberties Act of 1988 was an official apology made to Japanese Americans in 1988 by Congress. The act granted about US$20,000 to former internees who were still alive when the act was passed.

Repudiation of Korematsu v. United States
In 2018, Chief Justice Roberts, in writing the majority opinion of the Supreme Court in Trump v. Hawaii, stated in obiter dictum that the 1944 decision Korematsu v. United States that upheld the constitutionality of Executive Order 9066 (authorizing the Japanese American Internment) was wrong, effectively disavowing the decision and indicating that a majority of the court no longer finds Korematsu persuasive. Roberts also added: "The forcible relocation of U.S. citizens to concentration camps, solely and explicitly on the basis of race, is objectively unlawful and outside the scope of Presidential authority."
